akshitsharma-git/sumX ? reverse-engineered prompt

Build me a simple web app called sumX that lets someone paste an X post URL and get a short, clear summary in a few seconds.

I want a clean, minimal interface with a homepage, a loading state while it works, and a results view that shows the summarized post nicely. If the same post gets summarized again, it should come back faster from a cache. The app should fetch the post text from the URL, send it to an AI model for summarizing, and handle errors in a friendly way if the link is invalid or the request fails.

Use a React frontend and a Node.js backend with a small, production ready setup. Make it easy to run locally with environment variables for the scraping service, AI API, and Redis connection. If you need to check current docs or best practices for any of the services, go ahead and look them up online.
